【正文】 畢 業(yè) 設 計 題 目 哈爾濱圖書館七氟丙烷滅火系 統(tǒng)設計 院 (系 )別 安全工程學院 專業(yè)班級 姓 名 指導教師 職 稱 講師 I 摘 要 圖書館儲藏大量圖書和文字資料，不僅具有經濟價值，書籍本身更具有重大文化價值。圖書館本身作為大型公共場所，人員密度大，人口流動大，在火災方面藏有巨大安全隱患。本次設計是根據國家相關法律法規(guī)，對哈爾濱圖書館進行七氟丙烷滅火系統(tǒng)設計和火災自動報警系統(tǒng)設計。在七氟丙烷滅火系統(tǒng)設計中，將哈爾濱圖書館合理劃分為 22 個防護區(qū)， 對七氟丙烷滅火系統(tǒng)的設置進行了分析與計算。最終確定共需噴頭種類 JP— 1 JP— 1 JP— JP— 22共 4 種，噴頭數量總計 88 個。在火災自動報警系統(tǒng)設計中，將該圖書館劃分為 4 個報警區(qū)域和 50 個探測區(qū)域并進行合理設計。共選用了 110 個感煙探測器、 311 個感溫探測器、 58 個手動報警按鈕和 54 個聲光報警器。在設計的結尾部分，對哈爾濱圖書館本身的設計進行了安全疏散驗證且驗證合格，最大限度保證建筑內人員及財產的安全。 關鍵詞： 七氟丙烷；火災自動報警；安全疏散 II ABSTRACT There is an enormous amount of books and documents in the library. Not only has it economic value, but also has it significant cultural value. Tremendous as the library is, full of population, there must have some hidden safety. The aim of this graduation is to design the FM200 system and the automatic fire alarm system using a legal way in the Harbin library. In the FM200 system, it has been divided into 22 protection parts. According to the accurate analysis and calculation, it has finally decided to choose JP16, JP18, JP20, and JP22 around 88 nozzles. In the automatic fire alarm system, it has been fallen into 4 firealarm areas and 50exploration areas, including 110 smoke detectors, 311 temperature detectors, 58 manual warning buttons, and 54 audible and visual alarms In the end, the design has maximized to ensure the safety of evacuation and property. Keywords:Heptafluoropropane fire extinguishing system。The automatic fire alarm system。Safety evacuation I 目 錄 摘 要 .........................................................................................................................
